Vision develops rapidly in infants. At birth, vision is poor but infants can blink in response to light and stare at objects 8-10 inches away. By 1 month, infants can see some colors and follow objects up to 90 degrees. By 2-3 months, infants can shift their gaze between objects without moving their head and light detection improves. Stimulating activities like changing items in the room and talking to babies help vision development in 2-3 month olds. By 6 months, visual acuity improves greatly and color vision matches adults, allowing infants to see all colors. Regular eye exams starting at 6 months are recommended to monitor development.
Development of Vision
- 1. Vision Development Dr CSN Vittal
- 2. At birth • Poor eyesight • Infant will blink in response to bright light or touching eye • Eyes are sometimes uncoordinated, may look crossed-eyed • Able to stare at object if held 8 to 10 inches away • Initially fixes eyes on a face or light then begins to follow a moving object
- 3. In The First Month • Baby's eyes are not very sensitive to light in the first month of life. • Light detection threshold) is 50 times higher than that of an adult • At one week after birth, they can see red, orange, yellow and green • It takes a little longer for them to be able to see blue and violet. This is because blue light has shorter wavelengths, and fewer color receptors exist in the human retina for blue light. • Can follow an object up to 90 degrees • Looks at faces and pictures with contrasting black and white images
- 4. Months 2 And 3 • infants at this stage of development are learning how to shift their gaze from one object to another without having to move their head. • at 3 months old, an infant's light detection threshold is only 10 times that of an adult. • Follows light, faces, and objects
- 5. Months 2 And 3 • To help stimulate your 2- to 3- month-old child's vision development, the American Optometric Association (AOA) has these recommendations: • Add new items to their room or frequently change the location of their crib or existing items in the room. • Talk to your baby as you walk around the room. • Keep a night light on to provide visual stimulation when they are awake in their crib. • Put them on their stomachs when they are awake and you can supervise them. This provides important visual and motor experiences.
- 6. Months 4 To 6 • Visual acuity improves from about 20/400 at birth to approximately 20/25 at 6 months of age. • Color vision should be similar to that of an adult as well, enabling your child to see all the colors of the rainbow. • Better eye-hand coordination at 4 to 6 months of age, allowing them to quickly locate and pick up objects and accurately direct a bottle (and many other things!) to their mouth. • Will look at self in mirror • Will look at own hand • Six months of age - child should have his first children's eye exam. (AAO)
- 7. Months 7 To 12 • Better awareness of their overall body and are learning how to coordinate their vision with their body movements. • Begins to have depth perception • Can look for hidden toys • Can watch objects that are moving fast • Strabismus at this age can lead to amblyopia
- 8. 12 to 14 months •Recognizes own face in mirror •Recognizes familiar objects and pictures in books, may point to some objects when asked, "Where is the ...?"
- 9. • 36 to 38 months : • Able to focus on objects near and far • Picture matching • 36 to 38 months : • Vision is nearing 20/20 • Letter matching of single letters (Sheridan Gardinar Test) • (4 to 6 years) : • Has complete depth perception
